DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a structure for mounting a battery pack which is detachably mounted on a portable wireless device.

[0002]

2. Description of the Related Art In a portable wireless device of a type in which a battery pack containing a battery for a power supply is attached / detached, it is necessary to ensure the operability of attaching / detaching the battery pack and the waterproofness of an electrode portion. A proposal has been made.

FIGS. 5 (a) and 5 (b) are a side view and a front view showing an example of a battery pack attaching / detaching structure in a conventional portable radio, and FIG. Such an inverted T-shaped guide protrusion 3 is provided, and positive and negative terminals 4 are protruded from the bottom surface of the guide protrusion 3. On the upper surface of the battery pack 2 which is attached to and detached from the bottom surface of the portable wireless device main body 1, an inverted L-shaped guided rail 5 that matches the outer shape of the guide projection 3 on the bottom surface of the wireless device main body 1 is projected and provided. Is provided with an electrode 6 that can be connected to the terminal 4 on the bottom surface of the wireless device main body. A lock hole 7 is formed at the end of the upper surface of the battery pack 2, and a lock piece 8 that can be fitted into the lock hole 7 is formed at the end of the bottom surface of the wireless device main body 1 by a spring (not shown). Support in the state of being biased. The main body 1 of the wireless device and the battery pack 2 are connected by inserting the guided rail 5 into the guide projection 3 as shown in FIG.
The end 5a of the guided rail 5 is the stopper 1 on the main body 1 side.
The connection is completed when the lock piece 8 is fitted into the lock hole 7 when it comes into contact with the a.

The conventional detachable structure has an advantage in that the battery pack can be easily attached and detached, and it is difficult for the battery pack to come off even if the lock is released. However, since the waterproof structure of the terminal portion connected to the electrode on the battery pack side is not sufficient, problems such as electric contact due to infiltration of rainwater are likely to occur. Also, the guide projection 3
Since it is difficult to manufacture the wireless communication device 1 and the wireless device main body 1 by integral molding, the guide projection 3 is a separate component, which causes a problem of an increase in the number of assembly steps due to an increase in the number of components.

The portable wireless device main body 10 has a main body side connection mechanism 11 on the bottom surface, and the connection mechanism 11 is a battery pack side connection mechanism 1 provided on the upper surface of the battery pack 12.
3 is configured to be detachably mounted.

The main body side connection mechanism 11 includes L-shaped guide rails 15 protruding downward from both ends in the width direction of the flat first bottom surface 14 and facing each other. A pair of terminals (main body side terminals) 16, 16 protruding forward in the portion, an elliptical cylindrical sleeve 17 protruding forward to surround the outer peripheral portion of the terminal, and the sleeve Second bottom surface 1 which is the lower surface of 17
A lock claw 19 protruding from the rear edge of the guide rail 8 and stopper surfaces 20, 20 that are inclined and extend toward the second bottom surface 18 from a proper rear portion of the lower surface of the guide rails 15, 15. Have. The front ends of the guide rails 15 and 15 are located at a depth of a predetermined distance 1 (ell) from the front end of the first bottom surface 14.

The battery-pack-side connection mechanism 13 includes a T-shaped guided protrusion 22 extending from a position at the back of the front end of the bottom 21 by a predetermined distance toward the back, and a front end surface of the guided protrusion 22. Between a receptacle 23 having an elliptical cylindrical shape protruding from the receptacle 23, a rubber ring 24 fitted in a groove 23 a formed on the outer periphery of the receptacle 23, and guided rails 22 a protruding from both end edges of the guided projection 22. Inner ends 15 of the guide rails 15 of the main body side connection mechanism 11
a, bottom surfaces 25, 25 forming a space S for receiving a, 15a, stopper surfaces 26, 26, which are inclined surfaces connecting the bottom portion 21 and the side bottom portions 25, 25, and the bottom portion 2
And a lock hole 27 which is located at a front edge of the lock member 1 and which detachably fits and supports the lock claw 19.

The protruding portions 28, 28 located at the far end of the upper surface of the guided protrusion 22 are provided on the guide rail 15 on the main body side.
And the distance 1 between the first bottom surface 14 and the front edge of the first bottom surface 14. The battery pack side connection mechanism 13 is inserted from the front end side of the main body side connection mechanism 11 to the front end side of the main body side connection mechanism 11 so that the inner ends 15a, 15a of the guide rails 15, 15 of the main body side connection mechanism 11 fit into the space S.
